BLASTlNG-CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 289,764, dated December 1883.

Application filed August 7, 1883.

T0 at whom 731'; may concern.-

Be it known that I, SILAS R. DIVINE, of Loch Sheldrake, Sullivan county, State of New York, and a citizen of the United States, have invented an Improvement in Blasting- Gartridges, of which the following is a full, clear, and exact specification.

The object of my present invention is to facilitate the explosion of a blasting compound, which is composed of two ingredientsa solid and a liquidthe solid being such as powdered or crushed chlorate of potash, and contained in a porous envelope or cartridge-case, and the liquid being such as dead-oil, the said solid and its envelope being impregnated with the said liquid.

My invention, which involves the employment of a compound of this character, and in which the necessary combination of the said ingredients is effected by causing the solid to absorb the liquid, consists in a cylindrical envelope or cartridge-case of cloth, paper, or other porous material containing a solid substancesueh as crushed or powdered chlorate of potashwhich, together with said envelope, is impregnated with a liquidsuch as dead-oiland to which envelope is adherent, and more or less filling the interstices thereof, sulphur in a finely-powdered state. The compound which can be used for this purpose I have made the subject of a separate application for Letters Patent, and it is preferably composed of crushed or powdered chlorate of potash, or perchlorate or permanganate of potash, as the solid ingredient, and dead-oil as the liquid ingredient, the proportions being, say, about seven and one-half parts of the solid to one part of the liquid; but for the purposes of this present invention other fluid hydrocarbons than dead-oil which are practically non volatile in a free state at ordinary temperatures, or anitro compound-such as nitro-benzole-may be employed to form the liquid in gredient, and in such cases the proportions (X0 specimens.)

stated are desirably varied somewhat in the compound.

The solid ingredient of the compound be ing inclosed in a porous envelope or cartridgecase, is thus prepared for handling and transport with safety, it being in itself non-explosive; and the completion of the compound as an explosive is then effected by the consumer, when its use is required, by simply causing the liquid to be absorbed by and to impregnate the solid and its inclosing-envelope. Then, to constitute the subject of this present invention, the said envelope is coated with sulphur in a finely-powdered state, the sulphur, owing to the wet or moist or sticky condition of said envelope, impregnated with the said liquid, adhering thereto, and more or less filling the interstices thereof. The sulphur-eoatin g may be eii'ected by sitting the sulphur over the en velopes or by rolling them in a pan in which is the sulphur-powder. By thus coating the envelope containing the said ingredient, impregnated with the liquid ingredient with sulphur, I constitute an explosive which is in a convenient form for use in blasting, and which possesses increased susceptibility to explosion.

What I claim as my invention, and desire to secure by Letters Patent, is

The improvement in blasting cartridges herein described, which consists of a cylindrical envelope or eartridge-case of cloth, paper, or other porous material containing asolid substancesuch as crushed or powdered ehlorate of potash which, together with said envelope, is impregnated with a liquidsuch as dead-oil-and to which envelope is adherent (and more or less filling the interstices thereof) sulphur in a powdered state, substantially as and for the purpose set forth.

SILAS It. DIVINE.
